'lClaims.

The invention relates to improvements in water-proof paper containers and the primary object of the invention is to provide a convenient, economical, efficient and attractive appearing container that may be used for packaging and transporting ice cream in its usual semi-solid condition or other analogous food products that may partake of a semi-solid or partly liquid form, and which is particularly adapted to be easily removed from the food package while the contents thereof are in solid or semi-solid form in order that the contents of the package may be completely freed on all but one side thereof, at least, .from the package with ease and facility to permit the contents to be" cut into a plurality of slices or other smaller portions in serving the same.

A further object of the invention is to provide an improved form of paper container for frozen ice creamand analogous food products that or body ofthe contents of ,the container to assist in subdividing the food body within the container for convenience in serving.

It is a further object of the invention to generally improve the form, construction and mode of operation of water-proof containers made of paper or thin fibrous materials that are espe-' cially adapted for packaging frozen ice cream and analogous food products.

It is a further object of the invention to pro-' vide an improved two-part container made of paper or other analogous or water-proof paper in the form of two telescoping integral blanks that may be assembled for completing the package and disassembled for the purpose of freeing the contents of the package in the form of a block or loaf for accessibility.

It is a further object of the invention to provide an improved form of integral blank comprising a body portion and a plurality of foldable flaps adapted to be folded into the form of a closed container and retained in such condition' by a telescoping tube-like envelope which is adapted to surround the normal side walls of the carton.

-It is a further object of. the invention to provide a composite or two part, knock-down container for food products'consisting'of a collapsible inner carton formed of an improved blank of water-proof paper or ing a body portion and a plurality of foldable flaps of a form capable of being set up or expended-to form a collapsible closed, substantially proximately on the analogous material havliquid proof carton, and being held in its set up or assembled material containing form only by a closely fitting, telescopic, tube-like, detachable outer sleeve, the removal of which will freely permit the opening of the inner carton to 5 a substantially flat condition for exposing-and serving the contents thereof.

Other objects of the invention will appear from the following description of the invention which is directed to the preferred embodiment thereof 10 as illustrated in the accompanying drawings forming a part of the specification, the novel features being set forth more specifically in the appended claims.

In the said drawings:

Fig. 1 is a perspective view of a complete composite container embodying the invention.

Fig. 2 is a view similar to Fig. 1 showing the upper closure flaps of the container in open or receive.

Fig. 3 is a perspective view of the tubular cover or shell detached from the composite device of Figs. 1 and 2 and Fig. 4 is a sectional view ap 25 plane'determined by the lines 4-4 of Fig; 3.

Fig. 5 is a plan view of the blank showing the manner in which it is formed and scored to produce the tubular cover open at both ends in the form of a frustum of a pyramid for receiving and retaining the inner formed and folded blank of the container.

Fig. 6 is a plan view of the complete. blank showing the manner in which it is scored and also cut to form an irregular outline to produce the required panels forming the sides of the container when folded as well as the integral bottom part thereof and to which certain described fiaps are integrally attached-for forming the container into a complete closure.

Figs. 7 and 8 are vertical detail sectional views taken upon .planes at right angles to each other substantially as defined by the lines 1-! and 8-8 of Figs. 8 and 7, respectively, the view in the inner container blank of Fig. 6, the expanded blank being shown in-plan in Fig. 10 while Fig. 11 is a vertical sectional view through the container formed by completely folding the blank to its operative condition but without the cover or shell of FigfE, and Fig. 12 is a horizontal secfor the packaging of ice cream or analogous food products that will contain moisture, I preferto use a medium grade of paraffined paper board although it would be apparent that various creasible water-proof materials may be used in making the blank for the inner portion of the container. Q Although it will be apparent that the invention might take the form of a perfect cube or a parallelopiped whose angles are all right angles, I moreover prefer, forvarious reasons that will appear, in the manufacture of my improved container for ice creams and other dairy products as well as food products such as oysters, pickles and the like, to make the container in the general form of an inverted frustum of a pyramid, that is, having the smaller end of the container toward the bottom as in ,a form of previously well-known paper cartons or buckets heretofore used for like purposes as herein mentioned. 1

Since myimproved container comprises two separate co-operating portions, this frusto-pyramidal or downwardly tapering form of the side walls of the package is advantageous in'retaining the two parts of the container together in their assembled operative relations, particularly if it should be desired to attach a bail or some other suitable carrying means to the out-.

er or upper end of the tubular'cover portion of the container; therefore, the complete cut and scored blank as illustrated in Fig 6 and designated generally by the reference character In willconsist in a general way of two large par-. allel side walls or panels designated by reference charabters II and I2 defined by the scored lines and connected by the integral bottom portion l3, also defined by scored. lines as illustrated in Fig. 6 upon which it is desired that the blank shall bev creased for folding the blank expanded container blank.

By further reference to Fig. 6 it will be seen that the integral blank body is extended longitudinally and laterally from the panels ll, I2

to form certain foldable portions and flaps to complete the container; for example, on the two opposite sides of the panel H, there are integral panels M, ii and on the sides of the panel I2 there are similar laterally extending panels I6, I! cut to the form and purpose illustrated in Fig. 6. The material of the blank atsubstantially the outer edges of the panels I4 and i5 will be extended beyond the scored lines forming the outer ends ofthe panels Hi, 15 as illustrateduby .the dotted lines in Fig; 6 and likewise beyond the scored line defining the upper en l of the panel H, the material of the blank bod will also be extended as an integral part of the blank, and notches l8 and I9 provided extending down to the scored lines which define the,outer boundaries of the parts II, It, and I5, thus pro.-

ducing a substantially rectangular upper end closure flap 20 integral with the panel H and the irregularly shaped flaps 2|, integrally connected'to the panels l4 and I5 and carried thereby for co-operation with the other described flaps for forming a closure at the upper end of the container.

The blank I0 is further suitably notched as illustrated at 22, 23 to produce foldable bottom flaps formed integrally with the bottom portion I3 of the container as designated by the reference characters 24, 25 and these flaps 24, 25 will be severed from their respective contiguous portions I4, l5, l6, and IT by the short cuts as designated at 26 thus putting the flaps in condition 15 for folding at an angle to the bottom member 13 when the blank I0 is assembled to its set up condition in forming the complete container.

The before-mentioned substantially rectangu lar top flap 20 will be provided with a median 20 slit 21 designed to act as a keeper or retaining means for a. protruding tongue 29 formed as an integral part of the portion 28 at one extremity of the panel 12. 1

Referring to the blank for forming the outer 25 or tube-like cover as illustrated in Fig. 5, it will be seen that this consists of an integrally extending strip designated generally by the reference character 40 and it will also preferably be formed of a fairly stiff, substantial grade of pa- 30 per or analogous material, paraffined or otherwise suitably treated to give it waterproof characteristics when intended to handle the before mentioned food products as ice cream and the like.

4| and .42 are side panels of the cover blank designed inthe completed container, as will be seen, to overlie and be substantially co-extensive with the panels I I, I2 of the inner container, and they are connected by the intermediate narrower 4o panel 43 and to the terminal portions or panels 44, 45 respectively, all these portions from M to 45 inclusive being separated by suitably scored lines as illustrated so as to be foldable in relation to each other to form the assembled cover member of the container as illustrated in Figs. 1 3, and 4.

- As before indicated,-the foldable sheet 40 is v adapted to make a retaining cover for the package or' container that will give it permanent 50 forrh and retain the package in that condition; and to that end, the overlapping panels 44, 45 must be substantially secured together which may be done when they arebrought to the form illustrated in Figs. 1,- 3, and 4 by pasting them together using a suitable glueor adhesive or they may be permanently stitched together or otherwise suitably secured so that this outer sleeve or cover, which may be suitably decorated for ornamental or aesthetic or advertising purposes, may be a substantial supporting device capable, if a bail or other carrying means he attached thereto, of supporting the package or container for transportation.

The complete container incondition for receiving ice cream or other analogous material will be prepared and assembled in the manner illustrated in Fig. 2. The detail sectionalviews, Figs. 7, 8, and 9, most clearly illustrate the manner ,and sequence of folding the various panels and 7 a flaps of the inner container blank, from which it will be seen that the inner container blank In of Fig. 6 will be formed into'acup-like shape by bending the side panels II and I2 almost to the right-angle position on the'scored lines 50,51, 75

- smooth inside surface with may be made in cutting the material to allow for the space that is consumed in folding the panels around each other at the vertical corners due to the thickness of the material that is utilized.

In the sectional views through these substantially vertical composite end walls of the folded inner container blan as illustrated in Figs. 7 and 9, the panels l5 and II are shown as folded inwardly-to a substantially right-angular position on the lines of fold 5.4 and 55 and the co-operating panels l4, I5 are then folded over on fold lines 52, 53 to lie flat upon the outside of the panels 16 and I1. This will result in 'the formation of a closed container with the exception ofthe open top since the flaps then be in the condition illustrated in Fig; 2, but the inner container blank I is not designed to be permanently secured in its thus folded or setup condition and it will be apparent that in this condition the short flaps 24, 25'at the ends of the bottom portion l3 will still extend substantia lly in the plane of the bottom l3. However, in this position the inner container is in condition for insertion into the expanded and set-up outer cover device 40 and this will be accomplished by merely bending the short flaps 24 and 25 upwardly and dropping the inner container blank thus folded into the enlarged upper end 'of the holding cover 40 (Fig. 3) until the parts reach the position illustrated in Figs. 1 and 2 when the container will be in condition for filling as it is illustrated in Fig. 2 after which the top flaps may be folded to the closed positions for which they are adapted as illustrated in Fig. l, the flaps at the narrower side ends being folded over fiat upon the top of the contents of the inner package and the flap 20 next folded down on the overlapping flaps 2| after which the flap 28 maybe brought to the closed position and the flaps locked in their closed position by the insertion of the flap 29 into the slot 21.

The above described manner of folding the inner container blank, Fig. 6, will result in the formation of an innercontainer within the tubular cover 40 that will present a substantially to the material within the container. This is an important consideration in the use of the conta'iner for various materials, especially should it be desired at any time to dispense said materials from the container in an ordinary manner as by dipping the same therefrom with a'spoon or other implement since with my improved inner container folded as described-there will be no projecting flaps on the interior to interfere with'the removal of the material from the container. When the containeris used for the reception of ice cream and analogous food products the fact that it may at'some stage in its use contain some liquid, the fact that all of the joints-of the inner container blank ill will be covered by overlying thicknesses of the water-proof material when set up in the manner described wfll be apparent.

20, 2| and 28 will no projecting parts may be staggered and some stock saved.

An important feature of my improved container resides in its construction the same to serve as an economical and substantially perfect receptacle for food products if they melt and become liquid or. partially liquid but which, at 5 the same time,.are desired primarily to be retained in a solid or semi-solid form and to be served in that condition as by cutting the same in cubes or slices, a procedure that has not heretofore been feasible with ice cream containers of the general character or classto which the inan inner container of a collapsible and expansible nature is held in its operative condition. by the slidable or telescoping cover and these parts interlocked together against separation by sliding apart in one direction while freely separable when one of the parts is relatively moved in relation to the other in the, opposite direction to produce an improved container especially for use in storing, transporting and serving frozen ice cream and analogous products which makes it possible to serve the same in a manner not heretofore attainable in which the outer cover may be readily separable from the inner container and then leaving the inner container in condition to be freely opened with the block or loaf of food in a condition where it may be completely exposed on all except one side of the collapsible container blank Ill upon which it may rest, by merely re? leasing theflaps 20, 2|, and 29 and the flaps I 4 to H inclusive which wfll permit the enveloping container member III to be restored to its substantially flat position as illustrated in Fig. 6 when the block or loaf of food material still upon the flat blank if desired may rest upon a plate or platter for slicing or service in any other desired manner.

In Fig. 10 I show a container blank of special 40 construction like the blank illustrated'in Fig. 6 with the exception that it is modified so as to leave off the one pair of the overlapping panels at the ends of the substantially vertical parts of the inner container, preferably the parts l6 and ll, since it is found that there are certain food products that may be handled in containers of this character in a substantially solid or semisolid form where the question of providing a substantially liquid tight receptacle is not of paramount importance. In such containers the flaps l6 and I I may be omitted from the sides of the panel i2 as illustrated in Fig. l0 in-which the reference character 60 represents the entire blank. While the blank 60 thus constructed with out the flaps .l6 and I1. is not the preferred form the invention should take where materials that or likely to become liquid are to be handled, this modified form of inner container blank 60 may be used, and when so employed is slightly easier to fold and will result in some economy in the initial cost of production since in cutting the part 60 from a sheet of material, the various sections cut from the sheet of material In order that the invention might be understood, the details of the preferred embodiment have been set forth and described with particularity but it is not desired to be limited to the various details except as set forth in the claims as defining the scope of the invention.
